Overview
•
Get off to a fast start in automation solutions with embedded
PC platforms.
- Ready-to-use SIMATIC WinAC RTX or WinAC RTX F
preinstalled on EC31
- Prepared for use in a SIMATIC environment with PROFINET
and Industrial Ethernet
- Commissioning by specialist automation personnel as with
the S7-300
- Configuring and programming with SIMATIC STEP 7 over
Industrial Ethernet
- Optional visualization
•
Modular expansion capability:
Central expansion with
- S7-300 I/O (SM modules of S7-300)
- Expansion modules for additional PC interfaces, e.g. DVI-I,
USB, Gigabit Ethernet networks and memory card slots,
as well as PCI-104
•
Rugged operation
- Hard-disk-free operation based on flash disk and Windows
Embedded Standard
- Fan-free operation
•
Flexibility of a PC-based automation environment
- Free memory space on flash disk can be used for other PC
applications
- Use of WinAC ODK with SIMATIC WinAC RTX and WinAC
RTX F (read-only in safety-related program part)
- Connection option for USB devices
- Memory capacity expandable using multimedia card
•
Data retentivity for WinAC RTX and RTX F without uninter-
ruptible power supply (UPS)
■
Function
• Control:
For the optimum control of processes with WinAC RTX, several
processing levels are available:
- Cyclic program processing
- Interrupt processing
- Time and date-controlled processing
•
Functional safety with WinAC RTX F for EC31-RTX F:
The functional safety is implemented by means of targeted
safety functions in the software. Safety functions are imple-
mented with S7 Distributed Safety, to place the plant in a safe
state or to hold it in a safe state. The safety functions are
mainly included in the following components:
- In the safety-related user program (safety program)
in WinLC RTX F
- In the fail-safe inputs and outputs (F I/O).
The F I/O ensures reliable processing of the field information
(emergency stop pushbutton, light barriers, motor control). It
features all the hardware and software components required
for reliable processing, according to the required safety
class. The user only programs the user safety functions. The
safety functions for the process can be implemented with a
user safety function or a system-internal fault reaction
function. If the F system is unable to execute the actual user
safety function, it will execute the fault response function:
e.g. deactivation of the associated outputs and, if appro-
priate, F-CPU in STOP.
• Retentivity:
The controller can back up 512 KB of retentive data on an
integrated, non-volatile memory, without the need for a UPS.
Total retentivity of all process values of SIMATIC WinAC RTX
can be achieved with a generally available UPS.
•
Access to process values:
The SIMATIC NET OPC server supplied with EC31-RTX
permits open access to all process values. Visualization
systems or data processing systems can be linked to
SIMATIC WinAC RTX via this interface.
• Communication:
The Windows Automation Center (WinAC) is programmed with
SIMATIC STEP 7 via the integral Industrial Ethernet interface.
The SIMATIC NET SOFTNET Lean communication package is
pre-installed for this purpose.
•
Use of other software:
The customer can install supporting software products.
Windows Embedded Standard is designed so that typical
add-on packages can be installed.
